Description
The SJ-A1450 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the SJ-A1450 units with a logic “1" or open enables its pin 3
output. In the disabled mode, pin 3 presents a high impedance to the load. All units are designed to
survive wave soldering operations without damage.
Features
• Wide frequency range– 4.0MHz to 40.0MHz
• User specified tolerance available
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 3000g
• Metal lid electrically connected to ground to reduce
EMI
